Endogenously generated activated killer cells circulate after autologous and allogeneic marrow transplantation but not after chemotherapy.

After marrow transplantation, major histocompatibility complex (MHC)-unrestricted natural killer (NK) lymphocytes are among the first cells to appear in the circulation. After T-cell-depleted bone marrow transplantation (TD-BMT), these cells have an activated pattern of target cell killing; they also secrete lymphokines including gamma-interferon (gamma-IFN), interleukin-2 (IL-2), and tumor nec...

Cytomegalovirus infection after autologous bone marrow transplantation with comparison to infection after allogeneic bone marrow transplantation.

Cytomegalovirus (CMV) infection was detected in 65 of 143 (45%) autologous bone marrow transplant (BMT) patients. CMV pneumonitis occurred in only 2% of the patients and CMV retinitis occurred in none. Infection occurred in half of the 40 initially seronegative patients and 47% of the 94 initially seropositive patients. Among initially seropositive patients, platelet recovery was slower in infe...

Endocrinopathies after Allogeneic and Autologous Transplantation of Hematopoietic Stem Cells

Early and late endocrine disorders are among the most common complications in survivors after hematopoietic allogeneic- (allo-) and autologous- (auto-) stem cell transplant (HSCT). This review summarizes main endocrine disorders reported in literature and observed in our center as consequence of auto- and allo-HSCT and outlines current options for their management. Gonadal impairment has been f...

Study of Langerhans cells after allogeneic bone marrow transplantation.

We assessed the number of Langerhans cells (LC) before and after bone marrow transplantation (BMT) in 27 patients in order to study the fate and behavior of these dendritic antigen-presenting cells following allogeneic BMT. LC were identified using monoclonal antibody OKT6 on skin biopsies performed on days - 10, 0, 11, 25, 39, 120, and 365. In a control group composed of 15 healthy adults aged...

Generalized vitiligo after allogeneic bone marrow transplantation.

Sir, Vitiligo is a common, depigmenting disorder characterized by well-circumscribed cutaneous macules devoid of melanocytes on the epidermis. Bone marrow transplantation (BMT), which has significant therapeutic benefits in haematologic disorders, such as leukaemia and aplastic anaemia, provides convincing evidence for the role of the immune system in some autoimmune diseases (1). In this repor...
